11. Spark plasma sintered ZrO2-SiO2 glass ceramics and Si3N4 bioceramics
Abstract : This thesis focuses on elaboration and characterization of two types of bioceramics: one is ZrO2-SiO2 nanocrystalline glass ceramic (NCGC) for dental application. The goal is to develop new ZrO2-SiO2 NCGCs with a combination of high strength and high translucency; the other is biodegradable Si3N4 ceramics for spinal fusion. READ MORE

12. Fundamental Processes in SiO2 under Ion Bombardment
Abstract : Investigations of sputtering, electron emission and oxide growth under 40-300 keV H+, He+, N+, Ne+, Ar+, Kr+ and Xe+ ion bombardment of SiO2 are presented in this thesis. To accurately determine SiO2 sputtering yields, a new measurement method was developed where the electron emission was monitored during sputtering through thin SiO2 films on Si substrates. READ MORE

14. Thermodynamic study of the FeO-MgO-Al2O3-SiO2 system : Data assessment and phase diagram calculation
Abstract : This dissertation consists of assessed thermodynamic properties for phases in the geologically and industrially important system Fe-Mg-Al-Si-O and calculated phase diagrams. Mathematical processing of different kinds of experimental data (phase equilibrium data, calorimetric, volumetric, thermophysical,electrochemical, activity data) is used to derive internally consistent thermodynamic database.
